G2-Zero: Quantum Resilience for European Secure Communications

G2-Zero is an emerging deep-tech company pioneering quantum-based cybersecurity solutions, with a focus on safeguarding data for public institutions. Originating as a scientific spin-off, the company develops plug-and-play single-photon sources – miniature devices that generate individual photons on demand – to enable next-generation encryption systems. This highly specialized technology addresses a critical challenge: protecting government and defense communications against interception, including future threats from quantum computers. By harnessing advanced semiconductor photonics, G2-Zero’s innovation allows secure information exchange in fiber networks and via satellites, fortifying Europe’s digital resilience. Founded in Madrid amid Europe’s push for strategic autonomy in technology, the company has quickly drawn attention from NATO and European space programs. It represents a new breed of European startups translating laboratory breakthroughs into strategic capabilities. G2-Zero’s progress hints at a paradigm shift in how the EU and its allies will secure sensitive data – using quantum physics as the ultimate guarantor of confidentiality. This introduction highlights the company’s unique positioning at the intersection of quantum technology and cybersecurity, setting the stage for a deeper analysis of its strategic impact.
